TV shows aren't movies. The vast majority of television is produced on a budget which is directly based on what a network is willing to pay for it. This means that, unless a show goes massively over budged in production, a show that makes it to air is almost guaranteed to be making money. And as such basically every broadcast on TV is successful.
I finally think I understand your opinion. The position that everything is successful is a rational conclusion to reach, but there's a massive problem with it. You've been very vocal about being bored engaging in a logical breakdown of the issue, so I shall illustrate the problem using a quotation from a popular Disney movie.
Helen: Everyone's special, Dash.
Dash: [muttering] Which is another way of saying no one is.
If you brand every show on television a success - and using the logic you have employed at various points in this thread I struggle to think of a single show that wouldn't be considered a success, then your assessment of what constitutes a success becomes absolutely meaningless in an form of discussion. It becomes like one of those patronizing games produced for kids with special needs where everyone gets to be a winner - utterly worthless to everyone.
If everything is a success then success doesn't matter.
